RHF3M485 Lora Gateway Module High Isolation RS485 Data Forward Unit

High Isolation RS485 Data Forward Unit RHF3M485

Product Description

DFU (Data Forward Unit) RHF3M485 is a transparent transmission device form high isolation RS485 and RS232 to LoRaWAN transceiver which is designed by RisingHF. And the device integrates all LoRaWAN bands such as CN470, EU433, EU868, US915, AS923, AU915, KR920 and so on, and supports CLASS A and C.

RHF3M485 cover full LoRa frequency band of ISM sub-GHz, 433/470/780/868/915MHz. It will realize data transfer automatically through LoRaWan communication according to the integrated Application Data Transmission Protocol.

Benefit from the excellent wireless RF coverage of LoRa technology, thus saving the complex cabling projects and the cabling cost. RHF3m485 equipped with an isolated RS485 interface which withstand 1.5kVRMS isolation voltage between the interface side and UART side of the device.

RHF3M485 support wide range of input power supply, makes it more suitable for the industrial environment.
